Winter windstorm indicators for Europe from 1979 to 2021 derived from reanalysis

This dataset provides climatological indicators on European winter windstorms and their economic impact derived from ERA5 reanalysis. Also provided are risk indicators from a synthetically derived set of physically realistic windstorm events based on modelled climatic conditions. The primary users include the insurance sector, reinsurers and insurance industry service providers in response to their requirements for a catalogue of historic windstorm events within Europe. It is important for this sector to be able to characterise the temporal and geographic distribution of potentially destructive windstorm events over Europe. These data can also support sectors such as energy, transport, civil engineering and government.
The indicators available in this dataset are categorised as follows:

Windstorm tracks – the spatial track centred on the location of maximum relative vorticity above a threshold defining a windstorm as it moves over the North Atlantic Ocean and Europe.

Windstorm footprints – the maximum wind speed of gusts for each grid point of the domain during the passage of the storm over a period of 72-hours since the selected storm is first identified.

Summary indicators (Tier 1) – uses the windstorm tracks and maximum 10m wind speed to produce annual and decadal summary statistics for the land regions in Europe.

Loss and risk indicators (Tier 3) – describing the socio-economic impact of windstorms for various land cover and building types in Europe.

This dataset was produced on behalf of the Copernicus Climate Change Service.

本数据集提供了基于ERA5再分析得到的欧洲冬季风暴的气候指标及其经济影响。此外，还包括了基于模型气候条件，通过物理现实风暴事件合成集得来的风险指标。该数据集的主要使用者包括保险行业、再保险公司及保险行业服务提供商，以满足其对欧洲历史风暴事件目录的需求。对于该行业而言，能够表征欧洲可能造成破坏的风暴事件的时空分布至关重要。这些数据还能支持能源、交通、土木工程和政府等领域的应用。本数据集中的指标分类如下：

风暴路径 – 以超过阈值的最大相对涡度所在位置为中心的空间路径，描述风暴在北大西洋和欧洲上空移动时的轨迹。

风暴足迹 – 在风暴经过所选风暴首次被识别以来的72小时期间，区域内每个网格点的最大阵风风速。

总结指标（一级） – 利用风暴路径和最大10米风速，生成欧洲陆地区域的年度和十年度总结统计数据。

损失和风险指标（三级） – 描述欧洲不同地表覆盖和建筑类型在风暴中的社会经济影响。
